SPECIFICATION forming part of Letters Patent No. 245,053, dated August2, 1881.

Appiitanon mea Aprn 19, 1es1. (No model.)

,To all whom tt may concern:

Be it known that I, JAMES W. BODLEY,

lState of Louisiana, have invented certain new and useful Improvementsin Rotary Cultivators; and I do hereby Vdeclare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and'to lettersof reference marked thereon, which form apart of this specieation. p i

My invention is an improvement on the devices shown in Letters PatentNo.Y 239,219, granted March 22,1881, for supporting the rotary plows andtraction-wheels. In that patent the rotary disks were journaled` onswiveled standards with adjustable bearings and braces, for adjustmenttoward each other and to different angles to the line of draft. Theswiveled axle-standard was held in position from moving sidewise by aside brace attached to the cross-beam of the machine and to the standardnear the axle by means of a strap or -band connection.4 To this strap-orband was secured a spindle projecting outward from the machine, uponwhich the hand-lever having a traction-wheel attached was pivoted. Therewas also a brace attached to a plate or washer on the axlebetween thedisk and upright standard, extending to the forward cross-beam of the,machine. The draft-bar was also connected toV j this plate or washer onthe axle, the forward end supported bya chain secured to the crossbeamabove. `This mode of attachin g the braces to hold the axle-standard andsupport the vswin ging traction-wheels, and also the` manner ofconnecting the draft-bar, is not considered sufficiently strong andrigid for the work the machine has to perform; so I have devised a formof axle-support to which the brace-rods and draft-bar can be attached,possessing the requisite amount of strengthtand durability, that willovercome theobjections found in the other machine.

In the drawings, Figure lis a perspective view of the axle-support; Fig.2, detail views; Fig. 3, sectional view of a cultivator with theimproved axle-support attached; Fig. et, afront view of the same. Likeletters of reference refer to like parts.

rIhe letter A represents the axle-support, made preferably of castmetal, in two parts, b b', somewhat similar to a two-part joint-mold,the two sections being secured together by small bolts e o e.

B is a vertical tubular .bore in the body of the casting, of the samesize'as the axle-standard, around which it is placed. This tubular boreextends straight downward into the body of the casting a sufficientdepth of one size, and thence outward at right angles, graduallyenlarging on the sides into an oblong opening, c, of suflicient width toallow the axle to turn sidewise when it is required to adj ust the plowsin relation to the line of draft.

O is an axle-socket, consisting of a tubular bore in the casting atright angles to the vertical axis,'having conical studs h h on theopposite sides of the bore, which register into counter-sinks in theaxle7 to hold the same rm and prevent it from turning or pulling out ofits socket.

D is an axle to support the hand-lever, to which is attached thetraction-wheel.

' g g are eountersinks in opposite sides of the axle.

ff are projecting lugs, forming a bifurcated holdfast to receive the endof the side brace, to which it is secured by means of a bolt.

n is an eyebolt, to which one ofthe forward braces is fastened.

7c is a projecting lug provided with a bolti hole for the purpose ofattaching a draft-rod; E E E, frame of machine; F, swiveled uprightaxle-standard. J J J2 are braces; fi, draft-bar; K, hand-lever; L,traction-wheel. m m m are crank-handle nuts for fastening the braces andaxle-standard adjustably to the frame of the machine.

The axle-socket O can be made four-sided, with an enlargement at thebottom, in the man ner of a lewis-hole, and the axle made to correspond,and thus prevent it from turning or pulling out; or it could be madewith grooves in the socket and collar on the axle, or the converse, andother well-known ways, all of which I consider modications within thescope of my invention.

Having described my invention, whatIclaim, and desire to secure byLetters Patent of the United States, is-
